From IMDB: Following a stressful adventure, Rick and Morty go on a break to a spa where they remove their toxins, which in turn take a form of their own.

For me, this episode beats Pickle Rick. It has everything I want in an episode. The two-story arcs take place when Rick and Morty have their ‘toxic’ parts removed; each going on a journey to get things back to ‘normal’

Rick
I love this change in personality that the removal of toxins creates. Of course, it wouldn’t’ work in the long run, but I do expect there to be a development based upon what we’ve seen in this episode.

Morty
I love that the show acknowledges all the bits about Morty that I find incredibly annoying. It makes my opinion, that is ever changing, a little more validated.
The hatred I felt for sociopathic, Bateman-lite, Morty is way more passionate than regular Morty. This might be down to my current aversion to sociopaths, or the very fact it was a sociopath that got me into this show but I’m just so glad we got regular annoying Morty back by the end credits.

The ultimate thing that makes this my favourite episode is the Rick fight. It was the best, ever. Not too many Ricks, but their knowledge of each other made it genius.

Keep an eye out on my twitter @hscptcrash over the next few days as I will be putting up a Rick and Morty giveaway.
